Residential natural gas supply system

Abstract

The invention discloses a civil natural gas supply system, and relates to the technical field of compressed natural gas. The civil natural gas supply system comprises a gas cylinder, a frame, a high-pressure pipe, a pressure reduction adjusting device, a power adapter and a user gas stove. The gas cylinder is arranged in the frame, and a quick connecting male head is arranged at a gas cylinder outlet through a nipple connector. The quick connecting male head is connected with a quick connecting female head, and the quick connecting female head and the pressure reduction adjusting device are connected through the high-pressure pipe. An outlet of the pressure reduction adjusting device is connected with an inlet of a gas energy saving valve through a first hose. An outlet of the gas energy saving valve is connected with the user gas stove through a second hose. The pressure reduction adjusting device is provided with a pressure gauge and the power adapter. Stainless steel hose clamps are arranged at the two ends of the first hose and the two ends of the second hose. One end of a safety rope is arranged between the quick connecting male head and the nipple connector, and the other end of the safety rope is arranged at the joint position of the quick connecting female head and the high-pressure pipe. The civil natural gas supply system is simple in structure, safe, reliable, economical, practical and convenient to connect. The installing position is easy to select, the pressure situation of the gas cylinder can be observed, and the outlet pressure can be adjusted.

Description

technical field [0001] The invention relates to the technical field of compressed natural gas. Background technique [0002] my country has long used coal as its main energy pillar, and the proportion of high-quality clean energy utilization is relatively low. At present, promoting the substitution of natural gas for coal, which is vigorously advocated by the state, is the top priority for achieving sustainable economic and social development in my country, checking and balancing international constraints, and promoting reform. The formulation of the "Thirteenth Five-Year Plan" energy plan announced by the National Energy Administration will focus on achieving the two goals of increasing the proportion of non-fossil energy and reducing carbon emissions proposed by the central government. Civil gas accounts for a large proportion in the use of natural gas, so it is a good opportunity to develop civil natural gas supply system. [0003] The existing natural gas system for re...

Problems solved by technology

[0003] The installation of the existing natural gas system for residents is complicated. Residents cannot check the pressure of the gas cylinders by themselves, and cannot adjust the outlet pressure by themselves, which is inconvenient to use.
